Answer:
B. 7
Step-by-step explanation:
To find this out, first, we multiply 89*2, which is 178, the amount already spent on toner.
Then, we add 27 to this to find the total amount spent so far. This comes out to $205 spent so far.
To find out how much we have left to spend, we subtract the amount spent from the original.
400-205 = $195, the amount of money left.
To find out how much paper we can buy, we divide the cost of one paper box, by the amount of money we have left.
195/27 = 7.222222222222222222222222222222
Since we cannot buy 7.222222222222222222222222 boxes, we can only buy 7. This is the answer.
Answer:
your question is really not clear but if you were to put the -4 in the Y then the answer would be X=1/3, if you plug in -4 for X and find Y then Y = -17
Step-by-step explanation:
plug in -4 in Y
-4=3x-5 add 5 on both sides,
1 = 3x divide 3 on both sides
1/3= x
plug in -4 in X
y = 3(-4)-5 multiply 3 and -4 = -12
y = -12-5 subtract the -12 and -5 = -17
y = -17

Answer:
c = 12.5
Step-by-step explanation:
This is a right triangle so we can use the Pythagorean theorem (a^2 + b^2 = c^2)
lets say 10 = a and 7.5 = b (this is because they are the legs of the triangle and variables a and b represent the legs of the triangle)
plug into the Pythagorean theorem.
10^2 + 7.5^2 = c^2
simplify (here you just square 10 and 7.5)
100 + 56.25 = c^2
simplify
156.25 = c^2
simplify
(here you get the square root of 156.25 and c^2, the positive square root of 156.25 is 12.5 and the square root of c^2 is c)
12.5 = c
Answer:
g(3) = -5
Step-by-step explanation:
g(x) = -x - 2
g(3) = -3 - 2
g(3) = -5
